Table rendering throws ValueError (invalid width) for tables wider than screen
Summary
When we try to render a table that does not fit into a screen width (terminal width) a ValueError is thrown.
What happens
In the example below I have a table with 42 columns which is approximately 4x times wider than terminal's screen allows.
self.render_table(headers, rows)
ValueError
invalid width -9 (must be > 0)

What's expected
Either table is shrinked into given width or is rendered despite not fitting into the screen. Both options look ugly as hell though. More options are below
Fix suggestions
A. Fit table into terminal despite ugly outcome
B. Draw table wider than terminal despite ugly outcome
C. Somehow smartly draw the table in such a way that too long content becomes multi-line (already implemented somewhat). Also issue #47 talks about that option.
D. Add option to transpose table when redered (like \x flag does in PostgreSQL's psql command line tool)
E. Add option to break table into multiple pages where each page fits into screen
